SPEGlFIGATION forming part of Letters Patent No. 651,140, dated June 5,1900.

Application filed December 29, 1899. Serial No. 741,905. (No model.) I

T0 at whom, it may concern.-

Be it known that I, JOHN GoLnswoRTHY, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented certain new and useful Improvements in Trolley-Replacers;and I do declare the following to be a full, clear, and exactdescription of theinvention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

My invention relates to an appliance that is designed to perform thefunction of an automatically-operating guide for replacing a trolleywhen it may have left the overheadtrolley wire; and the objects of myinvention are to provide means of this character which shall be at alltimes instantly available and positive in action, so that accidents maybe avoidedas,for instance,when a trolley leaves the wire during the timethe trolley-car may be crossing a steam-railway track with a locomotiveapproaching. Under such circumstances the attendant may become excitedand unable to replace the trolley in time to avoid a collision, or hemay not be within reach of the trolley-rope and a passenger be tooinexperienced to replace the trolley. It is therefore my aim to providesuch a replacer as may be easily operated, and, if necessary, by aninexperienced person, even when excited to some extent. Experience hasproven thatit is impossible to practically prevent a trolley from eitherjumping or being thrown from the wire, and it is therefore highlydesirable that it be quickly replaced in emergency, and as well at allother times, in order to avoid loss of time and congestion of traffic.

With these objects in View my invention consists of apparatus adapted tobe attached to any type of trolley-pole and permanently carried therebywithout interfering with the usual operation of the trolley and withoutconflicting with the wire or its supports and switches, but which shallbe automatically brought into an operative position simultaneously withthe drawing down of the rope and end of the pole in the customary act ofreplacing the trolley, such apparatus including a frame fixed to thepole, a head pivoted to the frame, and movable guides mounted in thehead; and the invention consists, further, in the parts and combinationand arrangement of parts hereinafter particularly described and claimed.

Referring to the drawings, Figure 1 represents .a portion of the upperpart of a trolley-. car and trolley and pole in side elevation, showingmy invention in inoperative position,

-as when the car is in the electrical circuit;

Fig. 2, a similar view, but showing the trolley as having left the wireand being drawn down at the side thereof to again replace it, myapparatus being. in operative position; Fig. 3, a plan view of one ofthe guides and its supporting axial arm; Fig. 4, a front elevation ofthe upper portion of a trolley-pole and my apparatus attached thereto inoperative position, as when it has guided the trolley in alinement'withthe wire; Fig. 5, a side elevation of Fig. 4; Figs. 6, 7, 8, 9, and 10,detail views.

Similar letters of reference in the several figures of the drawingsdesignate similar parts.

In constructing my apparatus I provide a suitable metallic frame 0,adapted to be immovably secured to either a wooden or metallictrolley-pole B, such as are mounted upon the top of a car, as A, theframe extending both above and below the point of connection with thepole and being provided at a suitable point above the pole with a pulleyI, mounted on an axle 'i, and the customary rope or cable runs over thispulley when controlling the pole and the replacer. The top 0 of theframe is preferably sloping from the top of the pole to a point abovethe top of the pulley I to serve as a guard and prevent damage to thepulley against the arms which may be employed in supporting thetrolley-wire in case of the trolley flying off near such an arm. At thelower part of the frame or opposite the pulley 1, below the pole, ispivoted a head I) of suitable form, as by means of a blade e, insertedin a jaw d, and a rivet or bolt f. In practice it is preferable to makethe frame 0 of two parts and bolt them together upon the pole at asuitable distance from the trolley 'G,

no change in either the pole or trolley being required. In lieu of thepulley I a suitable guideway may be formed, through which the cable or achain may freely slide without material frictional resistance.

The head D may be made in any suitable shape to provide journal-bearingsfor the sup ports of the guide-arms F and F and is suitably composed ofeither a stamping or a malleable-iron casting comprising a bodyportion,to the top of which is attached the jaw d or a blade to connect withsuch a jaw, and counterpart flanges m and n, in which are circularapertures 7t, forming journal-bearings. It being desirable to provide aguide for the rope J, I preferably attach the same to the head D in theform of a curved arm K, which projects from the center of the flange orand serves both as a stop for the guide-arms F and F in their rotarymovement and as a lever for assisting in elevating these guidearms totheir operative positions. The rope J works in a guide-hole Z in the armK and is provided with a ring R or an enlarged partadapted to stopagainst the arm without entering the guide-hole.

The guide-arms F and F somewhat resemble wings, by reason of theirformation and the manner in which they are radially connected, and arepreferably, but not necessarily, of such shape. They are alikeessentially, but as shown are modified slightlyin adapting one for theright and the other for the left hand side. WVhen made in the best form,they may be exactly alike. As they are shown each is formed of sheetmetal stiffened by a frame n, which is a continuation of the axial shaftE, to which the plate is secured. A head 20 is formed at the top of thearm N or operative edge, which is designed to operate against thetrolley-wire. Thus webbed, there are no openings to catch against thewirehangers; otherwise the arms may consist of skeleton work and berigidly attached to the shafts E or E, which are alike, and have each acylindrical journal portionj, mounted in the bearings 7c and suitablysecured against accidental removal therefrom. At the extremities of theportions 7' are secured the dogs L and L, one to each, which are adaptedto engage the curved arm K when the arms F and F are in their properoperative positions. At a suitable point removed from the axis (as theshaft E) of the arm F, as at c, I attach a link a, and a link a issimilarly attached to the arm F, the links being made of any suitablechain or cable sections and having their free ends attached to the endof the rope J or to an intermediate connecting-chain. The frames u u arecoupled by a yoke M, which is adapted to rest upon the pole B when theapparatus is not in operation to support the upper portions thereof; butI may obviously provide stops in connection with the frame 0 and head Dto accomplish the same end. The yoke has its ends turned over to formeyes it h, or it may be formed of parts bolted or riveted together, soas to provide that the arms are practically hinged thereto.

The

edges 19 of the arms are elevated, so as to pro vide a guard for theyoke. The relative positions of the guide-arms F and F when theapparatus is assembled are such that when not in use the tops N and Nare somewhat below the top of the trolley G and unobstructive, the armshanging at the sides of the pole B, and when in use the tops N and N aresituate in opposite oblique angles, the points 3 and 5' being about ashigh or slightly above the bottom of the groove in the trolley, theouter ends '15 and i being higher than the flanges of the trolley G andextending nearly in a line transversely to the trolley-wire.-

The whole apparatus may be made very light in weight and symmetrical, soas to be unobjectionable in the required situation.

While I show and describe the shafts E E as being journaled, it will beobvious that I may without departing from the spirit and intent of myinvention secure these rigidly in the head and hinge the arms F F tothem and provide simple steps for the arms elsewhere in lieu of thestop-dogs L L.

In practical use let it be assumed that the trolley G has left the wireII and has been forced above it by the spring-pole. The usual practiceis to grasp and draw on the rope J to again draw the trolley down to aproper level below the wire and replace it by side movements, the timerequired in finding the vertical plane of the wire being considerable;but in the present case the act of drawing the rope taut against theaction of the pole-spring causes the rope to run freely over the pulleyI and through the side aperture 1) in its frame and through theguide-hole Z, spreading the arms F and F somewhat, as shown in Figs. 2,4, and 5, when the ring R forms a contact with the arm K and tilts thehead D, so as to elevate the oblique-angled tops N and N to the properheight designed, as shown in Figs. 2, 4, and 5. Then by drawing upon therope the trolley is drawn below the wire, and with it the guide-arms,and a slight lateral movement, together with a slackening of the strainon the rope, causes one or the other of the guide-arms to form a contactwith the wire, as at H, Fig. 4, and immediately establish a circuit,while the oblique angularity of the top N or N of the arms will permitthe spring of the pole B to force the arms over laterally against thewire until the trolley is in line therewith, and then the simplereleasing of the strain on the rope permits the guide-arms to drop away,while the trolley engages the wire. Thus it will be seen that only thecus tomary manipulation of the trolley-rope is required.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. A trolleyreplacing guide including a frame, a head connected with theframe, a pair of guidearms pivotally supported by the head and normallydepending at the sides of the trolley-wheel in lines parallel to thetrol ley-wire, a link connected to each guide-arm, an elevated ropeway,and a rope running over the ropeway and connecting the links, wherebythe guide-arms maybe moved radially and upwardly.
